This invent-ion relatesto a mechanical radiator Ornament in which, the f movable i parts are adapted. to be operated through the medium of wind vorforceof air. An 4object of the inventionisthe provision Vof a novel device preferably'constructedto simulate a bird in. appearance and operation andk adapted to be mounted. uponthe radiator cap'of an auto-y mobile orother convenient location. The de# 1o vice of the inventionis provided with apair of movable members adapted to operate in unisony andA arranged tO imitate the ,wings ofa bird whereby simulation of a bird inv flight is eifectually reproduced` through.. internal l5 mechanism of the device by means'off wind alone lor the force of air created by. a moving vehicle in` conjunction, to someA extent,fwith the force of gravity `inthe downward swingingy movement ofthe wings.y

Other objects will appearhereinafter.

The. invention consists in the combinations and arrangements Of parts hereinafter described and claimed.

The invention will be best. understood. by

illustrated in the drawings, the` pregfe'rred embodiment of' the `device comprises a hollow Leasing formed vin'genera-l outline in imitation O f 'a bird and composed of upper section 12 and'lower section 13 secured together by bolt`14. The device ymay be conveniently supported on radiator cap 15 of ya motor vehicle `by means of bracket lsecured to section 13.,` The operating mechanism of the device is preferably mount'edupon a mounting plate 17.1which may be supported by bolts 18` and is adapted t'o extend transversely` through the interior of the device. Extending laterally'from the sides of the device are two wing members 19 and'20,

which are secured to linlis 21I and 22respectively, which projectinteriorally of thebody casing through side openings 2.3 and 24, re-

spectively,whichare of suiicient size to permit'. oscillatingv motion ofthe wings. Links 21 and'22 are journalled for rotational oscillationin bearing members 25 and,26, respectively..which inturn are pinned or Otherwise rigidlysecured tosegmental gears 27 and 28, respectively. Gear 27 is pivotally mounted relative tothe plate 17 by .means of. a post 29 which is'adapted to eritend'through an opening in plate 17 for oscillatoryy movement relative thereto. Pivotally mounted upon post 2901i the opposite side. of plate 17 from gear 27 is a segmental gear 30, and this portion of the. device is secured in operative position by v'washer 31 engaged by. nut 32 threaded' on post 29. The. construction is such that segmentalv gear 30. is adapted to swingupon an axis coincident with segmental gear 2.7., but independently thereof,.and these parts coact automaticallyy to properly manipulate thefassociatedwing.. l l' l I lIt^ will` be noted that gear 27'meshes with gear V28 whereby they are adaptedtooperate i in unison, and the latter gear28islikeyvise provided with a post 33 which is journalled in` plateV 17 and uponv which is pivotally mounted segmental `gear34 held in place by washer 35and nutBS. Gr'ear V34 is adaptedy to means of which the link 22 is oscillated in bearing block 26. By reference to Fig. 5, finger 37 extends through an arcuate slot 38 provided inV gear 28, thence through an arcuate slot Y39 provided Vin the stationary yplate17, and thence through al relatively smaller opening 40 in gear 84. `llhen wing 20 is in its lowermost position, nger 87 is in thev full line osition `shown in Fig. 5,

E but as wing 20 is carried upwardlymby wind action, as presently described, finger 37 contacts with the end wall L11 .of slot 895 causing finger 37 to be-rocked'to the dotted line position shown in Fig. 5,v and'simultaneously`A gear 34 is swung downwardly bymeans ofl engagement of `finger 37, in openingO'. 'ln the position shown'in F igy, wing 20 'is in the dotted line position shown in Fig.r2 and the full line position shown in Fig. 3 withthe under surface of' the wingV in the Vpath of the wind. ,The force of wind against this surface causes wing 20 to be elevated tothe full line position shown in Fig.' 2,d and as l the wing Yapproaches this position, connectreversed. Link 21'has'a turned finger portion 42 `which `extendshthrough slotV 13 in gear 27, thence through slot 44: in plate 17, and thence through opening 45 in gear 30. By reference to Fig. 5 it will be noted that downward movement of wingv 2O is limited by contact of linger 87 withthe upper end walllll' of slot 39, andslot 44 i's likewise provided withA end wall portions corresponding` n to portions 41 and 46 of slot 39,. It has been found in operation that the forward gears 27 and 28 coact to insure unisonous vertical oscillation of the wings 19 and`20, whereas the rearwardly positioned gears 30 and 34 coact to maintain rotational oscillation in unison of the links21 and 22, and correspondinglyV the wings secured thereto. When the device is `mounted upon the radiator cap, for example, of a running. automobile, the force of air or wind is such that the Oscillation of the wings is quite rapid and the device closely resembles aliving bird in flight. y Y. i

It has been found desirable to construct the wings 19 and 20 of material light in weight, and aluminum has been found very satisfactory for this purpose. However, because of the relatively excessive strain placed upon the wings they are preferably strengthened bythe provision of corrugations 47 extending around the border portion.'4V`

pair of links journalled in said gear inem-V bcrs, a pair of wings secured to said links, a linger portion on each link, and a second pair of coacting gear members adapted to engage said finger portions to cause oscillation of said links, said second pair ofgeai members' mounted substantially co'az'zially with said rst mentioned gear members. f
